Application December 20, 1940, Serial No. 371,033

8 Claims. f (Cl. Ill- 65) My invention relates to a device to be used inpainting one of two adjacent surfaces, such as for example and moreespecially, the sash members of window sashes, for the protecting of thesurface not to be painted, as for example, the panes of glass of thesashes, against access thereto of paint in the painting operation. Moreespecially it relates to a device for the purpose set forth provided asa tool which the painter. by the use of one hand, applies to operativeposition, holding it in place while he paints with the other hand,shifting the device into successive positions along the article to bepainted as the painting proceeds.

One of my objects is to provide a device for the purpose set forth,particularly for the painting of window sashes, by the use of which thepossibility of paint becoming deposited on the part to be protected inthe painting operation and the smearing of paint on such part in the`manipulating of the device, particularly out of operative position, willbe avoided.

Another object is to provide such a device which will not require, forthe accomplishment of the object above mentioned, great care in themanipulation thereof into and out of operative position, and successivepositionings thereof may be quickly effected without depositing orsmearing paint on the part to be protected; and other objects as will bemanifest from the following :I

description.

Referring to the accompanying drawing:

Figure 1 is a plan view of my improved device.

Figure 2 is a fragmentary view in section of a window sash to be paintedshowing my improved device in section applied to operative positionthereon, the section through the device being taken at the line 2 onFig. 1 and viewed in the direction of the arrow; and

Figure 3, a similar view of the structure and device shown in Fig. 2,illustrating the manner of operating the device out of operativeposition, the section through the device being taken at the line 3 onFig. 1 and viewed in the direction of the arrow.

Referring to the illustrated embodiment of my invention, the devicecomprises a blade portion 4 preferably of Very thin sheet material asfor example and preferably spring steel of about 26 gage, having anobliquely disposed flange portion 5 at its rear edge to which a handle 6by which the device may be manipulated and shown as upwardly andrearwardly inclined, is attached, as for example by means of a rigidplate I secured to the flange portion 5 midway between its ends in anysuitable way as for instance by welding it thereto.

Located at the underside of the flange portion 5 at different pointstherealong, are members 8 in the form of buttons of material of suchcharacter that it tends to cling to a surface, such as for example apane of glass, to which it is applied and thus prevent slipping of thedevice on such surface, such a material for example being soft rubber.

The buttons 8 which are secured to the flange portion 5 in any suitableway, as for example by means of headed studs 9 integral therewith andlocated in holes Sla in the flange portion 5 through which they arecrowded in assembling them with the flange portion, are of roundedcontour at their undersides, as represented at I0 at which roundedportions, which form a rocker surface, the device is adapted to beseated in use against the surface to be protected in the paintingoperation, as for example the glass pane II of a window sash I2 with theforward terminal edge of the blade proper 4 seated in the interiorlangle I3 between the sash member I4 and the glass pane II, asrepresented in Fig. 2.

Upon finishing the painting of that portion of the sash member I4 whichis in registration with the device, the device is removed from operativeposition and re-positioned at the end of the painted portion of the sashmember to perform its protecting function and the painting of thatportion of the sash member which is opposite the 11e-positioned devicecontinued, these alternate operations being repeated until the paintingof the sash is completed; or the device may be slid along from oneposition to the next.

As will be noted, the blade 4, when the device is in operative position,inclines forwardly toward the glass pane I I which is to be protected,presenting a thin edge where it extends into the interior angle I3, andthe parts of the device are so related as shown, that a wide clearancebetween the handle 6 and the glass pane II is provided, adapting thedevice in removing it from operative position, to be rocked on such partat the rocker surface I0 as shown in Fig. 3, whereby the front edge ofthe blade portion 4 moves in an arc away from the glass pane II, asrepresented by the curved line I5 and in the direction of the arrowassociated therewith, thus moving out of the interior angle I3 in whichit is positioned in use, without rubbing against the painted sash memberI4; the provision of the anti-slip surface at which the device engagesthe glass pane II preventing the blade 4 from sliding on the pane andthereby preventing accidental smearing of paint on the pane.

While I have illustrated and described a particular constructionembodying my invention I do not wish to be understood as intending tolimit it thereto as the same may be variously modified and altered andthe invention embodied in other forms of structure without departingfrom the spirit of the invention.

What I claim as new and desire to secure by Letters Patent is:

l. A masking device comprising a blade portion to extend at its forwardedge into the angle between a part to be painted and a part to beprotected against access of paint thereto in painting the other part,the device having portions spaced rearwardly from said edge and spacedapart along the blade and which bear against the part to be protectedand on which the device is rocked out of operative position.

2. A masking device comprising a blade portion to extend at its forwardedge into the angle between a part to be painted and a part to beprotected against access of paint thereto in painting the other part,the device having portions spaced rearwardly from said edge and locatedadjacent the ends of said blade and spaced apart along the blade forbearing against the part to be protected and on which the device isrocked out of operative position.

3. A masking device comprising a blade portion to extend at its forwardedge into the angle between a part to be painted and a part to beprotected against access of paint thereto in painting the other part,the device having rocker portions spaced rearwardly from said edge andspaced apart along the blade which bear against the part to be protectedand on which the device is rocked out of operative position.

4. A masking device comprising a blade portion to extend at its forwardedge into the angle between a part to be painted and a part to beprotected against access of paint thereto in painting the other part,the device having rocker portions spaced rearwardly from said edge andlocated adjacent the ends of said blade and spaced apart for bearingagainst the part to be protected and on which the device is rocked outof operative position.

5. A masking device comprising a blade portion to extend at its forwardedge into the angle between a part to be painted and a part to beprotected against access of paint thereto in painting the other part,the device having nonslip portions spaced rearwardly from said edge andspaced apart along the blade which bear against the part to be protectedand on which the device is rocked out of operative position.

6. A masking device comprising a blade portion to extend at its forwardedge into the angle between a part to be painted and a part to beprotected against access of paint thereto in painting the other part,the device having nonslip portions spaced rearwardly from said edge andlocated adjacent the ends of said blade and spaced apart for bearingagainst the part to be protected and on which the device is rocked outof operative position.

7. A masking device comprising a blade portion to extend at its forwardedge into the angle between a part to be painted and a part to beprotected against access of paint thereto in painting the other part,the device having non-slip rocker portions spaced rearwardly from saidedge and spaced apart along the blade adjacent its rear edge which bearagainst the part to be protected and on which the device is rocked outof operative position.

8. A masking device comprising a blade portion to extend at its forwardedge into the angle between a part to be painted and a part to beprotected against access of paint thereto in painting the other part,the device having nonslip rocker portions spaced rearwardly from saidedge and located adjacent the ends of said blade and spaced apart forbearing against the part to be protected and on which the device isrocked out of operative position.
